Do ten sisters bird need nest?

If the ten sisters want to breed, they need to prepare the nest, and they usually do not need to prepare.This bird is distributed in many places in my country, and the reproduction time in different regions is different.For example, in Sichuan, breeding will begin in mid -March, but in Guizhou, it will wait until April and September, and Guangdong is at the end of October.Usually you can breed about 2-3 nests a year, and some can even breed 4 nests.
